46、atibility: a) between equipment located in different consists, and b) between equipment and devices located within the same consist. One of the key success factors for the deployment of any technology is the standardisation and ensuring interoperability among various implementations. To facilitate i
47、nteroperability a conformance test should be implemented. In this part of IEC 61375, the TCN hierarchical structure deals with the train bus called the Wire Train Bus (WTB). No other busses are taken into consideration even though they are foreseen by IEC 61375. WTB has real-time protocols, which of
48、fer two communication services: c) process variables, a distributed, real-time database, periodically refreshed through broadcasting; d) messages, transmitted on demand either as: 0. unicast messages (point-to-point) or/and 1. multicast messages. WTB has a network management, which allows debugging,
49、 commissioning and maintenance over the network. This standard is structured into 8 clauses and 2 annexes. The clauses and annexes are listed and briefly described in Table 1.
